我正在尝试使用/测试 CuPy（8.1.0）的（实验性）AMD GPU 支持。简而言之：我有一个ImportError.

  • 我按照说明在 Ubuntu 焦点机器上安装 ROCm（使用 gfx906/Radeon VII (Vega 20) 卡）。
  • 从文档中，我设置了提到的变量（带有调整HCC_AMDGPU_TARGET的），ROCM_HOME和export PATH=$PATH:/opt/rocm/bin:/opt/rocm/profiler/bin:/opt/rocm/opencl/bin。
  • pip3 install -v --no-cache-dir cupy没有任何抱怨就成功了。由于该-v选项，只有一些编译器注释和警告
  • 现在，当我尝试导入 cupy 时，它会抛出一个ImportError.
In [1]: import cupy

The above exception was the direct cause of the following exception:

ImportError: CuPy is not correctly installed.
If you are using wheel distribution (cupy-cudaXX), make sure that the version of CuPy you installed matches with the version of CUDA on your host.
Also, confirm that only one CuPy package is installed:
  $ pip freeze

If you are building CuPy from source, please check your environment, uninstall CuPy and reinstall it with:
  $ pip install cupy --no-cache-dir -vvvv

Check the Installation Guide for details:
  https://docs.cupy.dev/en/latest/install.html

original error: No module named 'cupy.cuda.cub'

接下来我该怎么办？在编译过程中我应该寻找什么？提前致谢

总结到目前为止评论中的讨论：

  • 对于 CuPy v8.x（最新的稳定版本）：在 v8.1 之前，有问题的cupy.cuda.cub模块未构建在 ROCm/HIP 环境中，希望在 v8.2 中得到修复（请参阅票证）。
  • 对于 CuPy v9.x（主分支）：只要正确安装了 rocPRIM 和 hipCUB，它就应该可以工作。很可能是 OP 的本地环境设置不正确，导致cupy.cuda.cub模块未构建，因此ImportError.
